    Description

    FLIR K33

    Affordable Clarity for Frontline Firefighting

    The FLIR K33 delivers reliable thermal imaging performance in a budget-friendly package—ideal for volunteer departments, new crews, or expanding your TIC fleet. With a 240 × 180 thermal sensor and 4” display, the K33 provides crisp images even in total darkness and thick smoke.

    Powered by FLIR’s patented FSX® Flexible Scene Enhancement, the K33 sharpens edges and textures in thermal images, making it easier to detect structures, obstacles, or victims when visibility is limited. This helps improve orientation, situational awareness, and decision-making under high-stress conditions.
